Thinking about doing the EFI Connection 24x LS1 PCM conversion to your LT1 F-body? Here are the parts you need for the harness. This is a stock 96-97 LT1 F-body engine harness out of my 50k mile 1997 SS. It's nearly impossible to find an OEM harness this nice. The harness is not brittle, almost as clean as new, and has no broken connectors. This is the harness you need for the 24x conversion since it has the crank position sensor.

I also have the EFI Connection 24x DIY harness re-pin kit. You would need to re-pin this into the above harness for the conversion. Many folks have done it on this site. The DIY setup is brand new and sells for $100 through EFI Connection. This includes everything needed to convert a 96-97 LT1 harness for use with the LS1 PCM setup.

I'll sell them seperately or as a package.

-EFI Connection 24x DIY kit: SOLD
-OBD2 96-97 LT1 engine wiring harness from my 50k mile SS: $275 shipped

The EFI Connection harness new sells for $850 plus shipping. So, this setup plus 2-4 hours of time can save you over $500 on this setup. Plus, you can then re-sell your existing harness

 

exactly what I did on my car, you can point people to my ls1tech writeup on repin of the harness, really is straightforward.

 

Thanks Merim! Yeah, you have a very nice write up on how to re-pin the harness

 

I got the same kit too and will be using that thread Merim! Great write btw! Bump!

but back to this thread, someone by this from Jason and get moving
